Abstract

Accurately measuring the importance of nodes in complex networks has important guiding significance for the study of network structure and functions. Most existing node importance evaluation algorithms consider the relevant information of the node and its neighbor nodes, but ignore the influence of the topological structure between nodes on the importance of the node. To solve this problem, this paper proposed a node importance evaluation algorithm based on gravity model and relative path number. The algorithm firstly analyzed the effect of the relative shortest path number on the information dissemination between nodes, and considered the influence of factors such as non-shortest path and path distance, then defined the node importance by the sum of the interaction force between the neighbor node and the center node in the third-order range, and finally simulated it in six real networks. Experimental results show that the proposed algorithm can not only effectively distinguish the importance of different nodes in the network, but also accurately measure the importance of network nodes.
